while read -t 2 -u 4 RESULT
[...]
I thought the read -t 2 ... should timeout after 2 seconds if no data is received. Any idea why this hangs?
Does that work other than when reading from a pipe or live terminal? The -u is pointing it at a file descriptor, so that might hang it.
Also, is there a better way to test these ports? The system I am trying to test is limited - perl and awk are not installed.
I can't think of one on that limited a system.
Hope that helps,
